Title 39 › Part PART I— - GENERAL › Chapter CHAPTER 6— - PRIVATE CARRIAGE OF LETTERS › § 601
A letter can be carried outside the mail if it is in an envelope with postage paid by stamps or postage meter stamps, the envelope is properly addressed and sealed so the letter can’t be removed without damaging the envelope, the sender cancels the stamps in ink, and the envelope is marked in ink with the date of the letter or the date the carrier got or sent it. A letter can also be carried privately if the payment for private delivery is at least 6 times the rate then charged for the first ounce of a single-piece first-class letter, or if the letter weighs at least 12½ ounces, or if the private service is allowed under certain USPS rules (including 39 CFR 310.1 and 320.2–320.8 as they were on July 1, 2005). The Postal Regulatory Commission must issue any rules needed to make these conditions work.
